First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km.
35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So divide 35 by 3.5 And 3.5(√h) by 3.5.
10 = √H To get rid of √ do the opposite raise to the power of 2
10² = (√H)²
100 = H
You must be 100 kilometers above ground to see 35 kilometers
You can divide 45 by by 25 to get the pages per hour and it’s 1.8
I think it will be a solution. Hope it help!
Answer:
x^2 +3x +3
Step-by-step explanation:
(9x^2+3x+6)–(8x^2+3)
Distribute the negative sign
(9x^2+3x+6)–8x^2-3
Combine like terms
9x^2–8x^2+3x+6–8x^2-3
x^2 +3x +3
